This will be the day of the presentation of the results of yesterday's .
By the way, Arnold is to attend the on the following day, the 2nd.
He is to give a detailed talk as a person from the time of the <>.
Therefore, his stay in the Kingdom of Celuloa will be limited to this day.

"Then, please give us a report.
8:30 am. As yesterday, the <> began, facilitated by Marcel, the king's brother.
"Yesterday, thanks to the cooperation of Jin-dono and Makina-dono, we were able to conduct the measurement smoothly. I would like to take this opportunity to thank you.
Kiku Masukawa, deputy director of the Agricultural Research Institute, began.
"First of all, I would like to show you a map of the distribution.
"Oh."
An image is projected on the large magic screen.
With the help of Chelle and the Golem Maid of Five Colors, a splendid document had been created overnight.
"Let me start with an overview. The distribution of contamination concentrations is roughly concentric from here ...... where the center of contamination seems to be."
"Hmm."
As you move away from the center, the concentration decreases.
That seems to be the case.
Also, to the west is the upper reaches of the Border River, where the soil moisture is relatively high, so the concentrations tend to be somewhat lower.
"Indeed."
Concentrations of heavy metals on the west side were 20 percent lower than those on the east side, the control site.
"Could it be that this is simply due to the fact that less pollutants were sprayed?"
Here Delfina offered her opinion.
"From what I have seen, the west side is less important than the east side from a strategic point of view because of its proximity to mountainous areas. That is why the number of ......<> at that time was probably small."
"I see, Delphina has a point.
Delphina, who was frowning a little bitterly when she mentioned <>,.......
"...... Let's leave the reasons for that for another time and check the facts for now."
Deus ex machina said, and everyone nodded and decided to listen to Kiku Masukawa's explanation.
"We'll continue then. ...... One point of interest is this point."
The location indicated was southeast of the Borolon Wilderness.
It should be a .
Only there was one place where the concentration was clearly low.
You could say that it was almost completely uncontaminated.
"But looking down from , there was nothing in the surrounding area.
Makina says.
Yes, at least on the surface, the wasteland was the same as the surrounding area.
"It's strange that only that area was spared from contamination, isn't it?"
"Yes.
"You don't know for a fact that someone has decontaminated the area in the past, do you?"
"No, I don't think so."
Marcel, the king's brother, is also tilting his head.
"If the land was decontaminated in the first place, it's strange that they haven't turned it into arable land or residential areas.
"Well, I'm sorry to say, but let's put this on hold and hear the whole report first.
Marcel, as the facilitator, told them. Inwardly he, too, was eager to know the cause of the anomaly.
Kiku Matsukawa then resumed his explanation.
"...... Well, the distribution of the contaminants was roughly as expected, except for the point that we named <>.
In the <> the contamination is present down to a depth of about 20 meters, and at 30 meters the level of contamination is no longer a problem.
<, the concentration of contaminants drops to a safe level at a depth of approximately 10 meters.
<, the level of contamination is acceptable at a depth of about 5 meters.
"The contaminants are cadmium, arsenic, hexavalent chromium and organic mercury. Each accounts for roughly a quarter of the total."
"......umm......"
Since all of these substances are highly poisonous, everyone was relieved that the protective goggles, gas masks, and dust gloves were appropriate during the survey.
"If you know the name of the substance, you can make a magical tool to remove it. But at a depth of 20 or 30 meters, it will take time to remove it.
Jin says.
If it is just the topsoil, it is easy ...... to make a magi-machine like an earthworm and decontaminate the soil while sucking it in from the front and spitting it out from the back, but at a depth of 30 meters, the method would have to be changed. But at a depth of 30 meters, it seemed that the method would have to be changed.
"At ......, let's discuss the <>."
After reviewing the results of the survey, we discuss our concerns.
"Well, was there anything unusual in the soil in the areas with low concentrations of contamination?"
Arnold asked if there were any other characteristics of the materials other than the toxic substances.
"Not really, it's what we call normal ...... standard soil."
He said it was a mixture of clay, sand, humus, trace minerals, etc. "I don't feel like I know what caused it," he said.
"It's weird that you don't know the cause of the problem, isn't it?
"Yes."
"I think it is most likely that someone has decontaminated it. ......"
Jin says.
Because there is no way it could have been decontaminated naturally.
"Then who are they?"
Kiku Maskawa turned anxious eyes on Jin and Makina.
"I'll have to look into that. ......"
Makina murmured.
"I suppose you're right. We'll find out if we can find out anything about that unnaturally decontaminated area."
Jin said, "There might be some clues in the center of the uncontaminated area.
"Then I'll take care of that.
Makina said.
This was purely out of interest.
"I know how to do a soil survey from what I saw yesterday.
Besides, the measuring instruments were made by Jin and Makina, so they can produce as many as they want as long as they have the materials.
"How about ......, Your Highness Marcel?"
Jin asked his brother Marcel.
"Yes, it would be very helpful if you could look into it. I will issue a permit in my name.
"Thank you, Your Highness."
Since the investigation was to take place in the Kingdom of Selroa, it could not be done without a permit.
Thus, the deus ex machina was to conduct an additional investigation of the .
